Calculations with IsEmpty

[SkiSystems]

I would greatly appreciate any advice. I think what I am trying to do is simple, I just can not figure it out. I have a field "LotA" and a field "LotAcres". I am trying to write a calculation for LotAcres field that will automatically put 4.6 in to the field if the "LotA" field is NOT empty... If the "LotA" field is empty then the "LotAcres" field I want to remain empty.

 

Thank you for your help.

Hi skiSystems, welcome to FMForums. :-)

Would you ever need the ability to manually override or change that LotAcres?

If not then the field should a calculation (result is number) and look like this:

Case ( not IsEmpty ( LotA ) ; 4.6 )

If you need ability to override then it should be number with auto-enter by calculation and uncheck 'Do not Replace'.

Oops notice calc change adding another parenthesis.
